Let n be the 1st number, the 2nd is n+1
But we know that (n) + (n+1) = -49
2n + 1 = - 49
2n = - 49 - 1
2n = -50 and n = - 25 and n+1 = -25 + 1 = -24
the 2 consecutive numbers are - 25 and - 24

х is the first integer
(x+1) is the second integer

x + x + 1 = -49
2x + 1 = - 49
2x = -49 - 1
2x = -50
x = -25 first integer
-25 + 1 = -24 second integer

Answer: -25 and -24
